While both of those are cool bash toys, neither feel as satisfying IMO as Sparky with the integrated Magnet/sounds/callouts, etc. (feels more "alive" I suppose) Sparky may be my vote for #2 as well (partially due to the awesome multi-ball start-up sequence). TOM Trunk I also find to be a more fun bash toy, but perhaps not as consistently rewarding feeling. I think all three bash toys on TWD Prem/LE are fairly rewarding (at least with the Bicycle Girl light mod..otherwise just the 2).
While not consistently fun enough to name anywhere near #2, I give some honorable mention to Captain Spaulding during What mode, as I enjoy the insults and the slight playfield change when he swings open to complete the mode and collect jackpots on the upper playfield.
